In order to effect maintenance and repairs, India’s state-owned National Hydroelectric Power Corp. announced on Dec. 14 that it will stop generating power through February 2016 from its 520-MW Parbati III hydroelectric project on the Sainj River in Himachal Pradesh.
Parbati III has four 130-MW Francis turbines and each unit will see repair to their pressure shaft, static excitation system, main inlet valves, digital governor seals and additional maintenance, according to a filing from NHPC.
State-owned power equipment maker Bharat Heavy Electricals Ltd. (BHEL) commissioned the first three units in February and March 2014, and the fourth unit in May 2014 at the run-of-river scheme.
NHPC presently owns and operates a total of 18 hydro power stations in northern, eastern and northeastern India.
In 1981 BHEL set up NHPC's first facility, the 198-MW Baira Siul hydroelectric project in Chamba, Himachal Pradesh. The company's contribution to NHPC's total generating capacity now stands at 2,884 MW.
BHEL is currently executing three additional NHPC hydro projects that include 330-MW Kishanganga in Jammu and Kashmir; 160-MW Teesta Low Dam IV in West Bengal; and 800-MW Parbati II in Himachal Pradesh.
BHEL is a power plant equipment manufacturer and operates as an engineering and manufacturing company based in New Delhi. It is the country’s largest engineering and manufacturing company of its kind.
